Bona Retarder is a product that extends the processing time for Bona's water-based base and topcoats. If the humidity is low and/or the room temperature is higher than normal, you can use Bona Retarder. It reduces the risk of the paint drying too quickly and leaving rolling stops in the dried paint.
